Once upon a Pink Flower

This photograph was my FIRST ever nature photo I took and also the first image I took from my new camera over 2 years ago in Spring? I'm very proud of this work. The colors works great too.
I'm fairly very new to photography, so tips are very welcome!
This can be also used as stock, just, please credit me.
